Pilot Setup for Dynamically Enhanced Membrane Emulsification This setup allows the production of emulsions with narrow drop size distributions. A disperse liquid phase is pushed through a porous membrane into another immiscible fluid phase. A rotor above the membrane induces laminar shear flow, which detaches the drops from the membrane pores. A narrow shear gap and micro engineered membranes help to maintain good control over drop detachment. The sub pictures show drops detaching from membrane pores (top) at different shear flow conditions acquired in a separate visualization setup. The bottom picture shows a cut through a micro engineered silicon membrane, which was specifically designed and fabricated at ETH Zurich for the emulsification setup. The apparatus was designed and built by the Bühler AG, Uzwil, Switzerland in close collaboration with the ETH Zurich, Switzerland.
